Apple Lossless in Volkswagen
Hi guys, new member here with a question.  So I acquired some 88.2kHz/24 bit Apple Lossless Rolling Stones albums and discovered my iPod cannot play them.  Is there some type of an FM transmitter or hacked firmware I can use on my iPod, so that I can play these in my car?  As I understand it, iPod can only do up to 48kHz/24 bit and that's a quality degradation I don't want to take.

Preferably, I would like something that I could hook up a USB flash drive to. 


Vehicle is a 2008 Jetta Se and I have the AUX cable to my stereo, inside my glove box (not the MDI). 

Anyone have any suggestions?

Thank you.

Convert it to 44.1 kHz and burn that onto a normal Audio CD (or do a high-bitrate encoding in a lossy format your car radio or iPod supports, or any supported lossless format - this should also work with 24 bit). There should be no quality degradation detectable by human ears whatsoever.

As to why: I recommend reading http://people.xiph.org/~xiphmont/demo/neil-young.html

FM transmitters have a high chance of delivering quality degradation detectable by ears (noise and limited bandwidth).

FM stereo is limited to 16 khz, and with really good transmitter and receiver you can get about 75 dB S/N.  This is equivalent to 32 kHz/13 bit.  IF that is good enough for you, why is 48/24 (or 44.1/16) not good enough?

Both of which are considerably in excess of the thresholds of hearing of most adults.

Any competent down-convertor would achieve this completely transparently, so that no would ever hear any difference. Still, you shouldn’t “acquire” such pointlessly oversampled files if you don’t want to have to down-convert them for a majority of entry- and mid-level equipment.

Are the sources actually digital (and that freq/bitdepth) or rather analog tapes from forty-some years ago?
